A method of adjusting a power control setpoint threshold (216) in a wireless communication system is provided. The method includes the steps of receiving at a receiver, a communication signal from a mobile communication unit to form a received communication signal, generating a first signal quality indicator (193) based on the received communication signal, generating a second signal quality indicator (194) based on the received communication signal, and generating an estimated signal-to-noise ratio (98). The method further includes setting a predetermined reference region (605) centered around a second signal quality indicator reference (206) where the second signal quality indicator reference (206) is related to the first signal quality indicator (193), and adjusting the power control setpoint threshold (216) based on a comparison between the second quality indicator (194) and the predetermined reference region (605).
